пусть одного зовут Sam, a другого Fred
Sam: Hey, Fred!
Fred: hey, what's up, Sam?
Sam: How are you doing?
Fred: well, not really good.
Sam: why's that?
Fred: that's a long story
Sam: then why don't we go to the cafe and talk about it ?
Fred: I don't think that's a good idea..
Sam: oh come on, I insist!
Fred: well, okay then, let's go!
Fred: so, what's new in your life?
Sam: well, yesterday my wife and I went shopping and we found a very good clothes store!
Fred; oh, it must be an expensive one
Sam: oh no, it is pretty cheap. Do you think that a cheap shop can't be a good one?
Fred: yeah, you got me, that's exactly what I think!
Sam: and I don't see any difference, you can buy the same shirt in the expensive shop or in the cheap - it's still the same shirt!
Fred: yeah, but the quality is a big difference!
Sam: as I see I can't prove you that my point of view is right
Fred: yeah, let's just order something to eat!
